History
What size room are the Sonus faber Amati Supreme and Sonus faber Serafino speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Amati Supreme is a 5-way design whereas the Serafino is a 4-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Amati Supreme features a 1.5" Silk Soft-Dome Tweeter, a 6.5" Midrange and 2 x 8.5" Paper Woofer with a Crossover frequency at 230, 300, 1800, 5600 Hz. On the other hand, the Serafino features a 1.1" Silk Soft-Dome Tweeter, a 6" Midrange and 2 x 7" Paper Woofer with a Crossover frequency at 200, 250, 2400 Hz.
Frequency Response
Amati Supreme has a frequency range of 28-40k Hz whereas Serafino has a frequency range of 30-35k Hz. With a minimum frequency of 28Hz, the Amati Supreme can go slightly deeper then the Serafino's min frequency of 30Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Amati Supreme and Serafino have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Amati Supreme sensitivity is rated at 91 dB and the Serafino's is at 90 dB. This 1 dB difference makes the Sonus faber Amati Supreme a more sensitive speaker compared to Sonus faber Serafino, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Amati Supreme and the Amati Supreme can provide this impedance level.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Amati Supreme can handle a max power of 600 watts RMS, whereas Serafino has a max power handling value of 300 watts RMS, 300 watts less than the Amati Supreme.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.

Input Type and Bi-Amping / Bi-Wiring
Both Amati Supreme and Serafino features dual binding post speaker terminals for bi-amping or bi-wiring.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Sonus faber Amati Supreme's and Sonus faber Serafino's external dimensions. Sonus faber Amati Supreme has external dimensions of 1176.0 x 411.0 x 512.0mm (46-5/16 x 16-3/16 x 20-3/16inch) whereas Sonus faber Serafino has external dimensions of 1091.0 x 396.0 x 485.0mm (42-15/16 x 15-9/16 x 19-1/8inch).
Sonus faber Amati Supreme is clearly the larger of the two speakers. Its body is 15mm wider, 85mm taller and 27mm deeper than Sonus faber Serafino.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Sonus faber Amati Supreme needs about 10% more floor or shelf area. Sonus faber Amati Supreme is 27mm deeper, so it stands that much further out from the wall. Sonus faber Amati Supreme is 85mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Sonus faber Amati Supreme is approximately 2104.3cm2 / 326.2inch2 and base area of the Sonus faber Serafino is approximately 1920.6cm2 / 297.7inch2. The Amati Supreme requires 10% more surface area than the Serafino which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Sonus faber Amati Supreme weighs 62.00kg / 136.4lbs and the Sonus faber Serafino weighs 52.00kg / 114.4lbs. This makes the Amati Supreme 19% heavier than the Serafino.

Siblings in Sonus faber's Homage series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (28Hz vs 30Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (91dB vs 90dB) - both want much the same power. |
| Headroom | A | Sonus faber Amati Supreme takes more power (600W vs 300W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Sonus faber Amati Supreme: bi-amping; Sonus faber Serafino: bi-amping. |
| Price | B | Sonus faber Serafino is cheaper - $21,998 against $145,000, about 85% less; arguably a different class. |
A Sonus faber Amati Supreme B Sonus faber Serafino
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Sonus faber Amati Supreme is ahead, but only on 1 of the measured areas, and it costs about 6.6x the price. That is a lot of money for a narrow margin on paper - Sonus faber Serafino looks like the sensible buy unless something else about the Sonus faber Amati Supreme appeals to you. Think about the whole system, not just the speakers: the roughly $123,002 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
